Joint Spatial Division and Multiplexing (JSDM) is a downlink multiuser MIMO scheme
recently proposed by the authors in order to enable “massive MIMO” gains and simplified …

We consider the downlink of a time-division duplexing (TDD) multicell multiuser MIMO
system where the base stations (BSs) are equipped with a very large number of antennas …

We propose a new hybrid precoding technique for massive multi-input multi-output (MIMO)
systems using spatial channel covariance matrices in the analog precoder design. Applying …

Massive MIMO is a variant of multiuser MIMO (Multi-Input Multi-Output) system, where the
number of basestation antennas M is very large and generally much larger than the number …

We study multicarrier multiuser multiple-input multiple-output (MU-MIMO) systems, in which
the base station employs an asymptotically large number of antennas. We analyze a fully …

The use of space-division multiple access (SDMA) in the downlink of a multiuser multiple-

Massive multiple-input multiple-output (MIMO) is a breakthrough communication technique
for providing high spectral efficiency. The idea is to deploy a very large number of antennas …

This paper designs a novel hybrid (a mixture of analog and digital) beamforming and
examines the relation between the hybrid and digital beamformings for downlink multiuser …
